For the second time in the past week, officials have reported a bison attack in the region.

The Bismarck Tribune reports a bison bull attacked a seventeen year-old tourist Sunday in the South Unit of Theodore Roosevelt National Park.

A spokesperson for the park said the bison gored the back of the girl's leg and tossed her about six feet into the air.

Emergency personnel treated the girl at the scene and then transferred her to a Bismarck hospital for recuperation. As of late Sunday she was in "stable" condition.

Authorities say bison are currently in mating, or "rutting" season, which tends to make the bulls more aggressive.

Witnesses say the girl was walking along a trail when she stepped between two bison who had been fighting.

A week ago a nine year-old girl was tossed into the air by a charging bison at Yellowstone National Park.

Roosevelt Park officials advise tourists to stay at least 25 yards from any large animals in the park.
